Application Profiles

■ Application profiles define what messages are sent over the air for a given application

■ Devices with the same application profiles interoperate end to end■ ZigBee publishes a set of public profiles, but vendors may create manufacturer

specific ones as well

Why is Efficiency Important? - Macro Trend of US Energy Issues

“Electricity demand in the U.S. is expected to grow by 135,000 megawatts in the next decade while only 77,000 megawatts of new resources have been identified, leaving a shortfall of 58,000 megawatts , an amount equivalent to 110 large power plants.”

- WSJ October 16, 2006; on recent report from NERC


24


■ Legislative environment is waking up to the importance of consumer demand management

► 2005 U.S. Energy Policy Act

� The policy of the U.S. is to encourage time-based pricing and other forms of demand response and that deployment of devices to enable consumersto participate in these programs be facilitated.


25


■ Awareness of Global Warming spreads

► Former Vice President Al Gore addresses San Jose Embedded Systems Conference in April 2007


26


DOE Vision: “Smart” Devices

“Mechanisms to reduce peak demand include time-of-use pricing , load management devices such as “smart” thermostats , load-shifting technologies such as energy storage, and peak-eliminating techniques such as distributed generation and thermally activated heating, cooling, and humidity control devices.”

“Grid 2030” — A National Vision for Electricity’s Sec ond 100 Years; US Department of Energy

SCE’s Vision for Advanced Metering

SCE, Southern California Edison, envisions a potential advanced metering system as one that could bring customer usage and meter data into the digital “central nervous system” of its power operations. An advanced metering system could be the information backbone for technologies that measure usage and power quality, and enable dynamic pricing and demand response . The advanced system may enable customer-premise information and automation.

The scope of SCE’s metering solution is to replace approximately 5 million electric meters for SCE’sresidential, commercial and industrial customers (below 200kW in demand)…While SCE is an electric utility, we anticipate that the preferred solution would provide a communications network that could be leveraged by gas and water utilities in our service territory.

SCE’s AMI Program was recognized as the 2005/2006 Best AMR Initiative in a North American Investor-Owned Utility in August 2006 by the Utility Planning Network.


29

Emerging Drivers for AMI and HANs

Empower customers to manage their energy costs and provide new services through smart technology

► Create lasting customer value through cost-effective advanced metering technology solutions

► Design to support Federal and State Energy Policy Objectives

► Enhance competition in competitive retail markets

► Support energy efficiency efforts and reduce new supply requirements

► Support strategy of modernizing our infrastructure with smart technologies toward an intelligent grid

SCE Edison SmartConnect™ Program Objectives: Create 1,000 MW of new peak demand response

U.S. Home Energy Today

Today, 67% of the average household utility bill is attributed to temperature control and lighting.
